The Metric month is the four-week period of the Quaternary Metric World Calendar which lasts exactly 28 days, with the exception of Equatorial Month in the middle of the year and, once every four years, Southern Late Lent, which last 29 days. Every such month one idea, aphorism or statement suitable as a 'quotation' receives special attention in a trailer of the main document. It is called "the note of the Metric month". Such a 'note' may be serious or profound at one time and funny or light-hearted at another.

Until 57 years after the end of the Second World War (that is, the year 57 inclusive) the notes of the Metric months were put in one basic file named "Notes/Months.HTM". As this file was getting too long, they are now collected in files which cover four years, that is, 52 notes. The first ASWW year of each file is divisible by four. The collection starts with the note of the 52nd Southern Mid-Yule.

The following four documents are attached to this branch:

• Notes of the Metric Months from 52 to 55 ASWW
  
• Notes of the Metric Months from 56 to 59 ASWW
  
• Notes of the Metric Months from 60 to 63 ASWW
  
• Notes of the Metric Months from 64 ASWW
